Hi guys,

I'm reading a lot into intermittent fasting....i.e. where you eat normally 5 days a week and then eat 500 calories a day for 2 days a week.

Does it REALLY work?!

To tell you the truth that is not an IF protocol I'm familiar with. IF is no magic bullet for weight loss, it may be something to try out if you enjoy eating larger meals and is something that is more convenient for you

Is this after the Horizon programme on Monday night? There's a few threads on here already about it.

What do you mean by "work". The Horizon programme found it had useful health benefits, but it wasn't primarily a weight loss thing, that was just a side effect.

Any program that allows you to eat at a calorie deficit with macronutrient sufficiency will work, whether it's a leangains style IF, 6 meals per day, 3 meals per day, Eat Stop Eat, etc etc.

IMO the big difference is that some people will find one that fits their lifestyle and this helps a ton with adherence.

Yeh i agree. Do you know if it has to be 2 days in a row that you do the 500 calories? i could probably do it i think!

I have no idea but I was wondering the same thing. I would like to do a juice fast once a week. And just drink about 500-700 calories that day in fresh fruit/veggie juices.

I think that if you're going to do something like this you should have a good idea as to what your TDEE is and you should create a weekly deficit rather than a daily one so that your 500 calorie days are balanced by a higher calorie intake on one or more days.

Beyond that I'm not familiar with the specific program you're referencing.

hmmmm looks like i need to do a bit more research. I don't know if i could realistically manage it or if i'm kidding myself! xxx

From what I understood of the documentary, it doesn't have to be 2 days in a row - they could be spaced out however you like. I think it's just that for people who work Monday to Friday, it's likely to be more convenient to do the fasting at the weekend.

look into the alternate day diet by James Johnson MD
August 8, 2012 6:49 AM
Here is the original article on this....It's 5 days of eating whatever and 2 days in a row of 500cals....Or you can do the alternate days...1 day of eating anything and one day of 500cals and the next eat whatever and so on....The 5:2 sounds doable to me at least.

Oooo thank you!! I'm tempted to give it a go!! will be a challenge but im willing to try anything right now :) xxx

not familiar with that kind of IF style. IF is not for everyone, but i do find it easier to hit a cal deficit consistanly. which is the key really, what ever you choose. I do 16/8 everyday and a 20-24hr every once in awhile.

good luck.
August 8, 2012 7:22 AM
for those doing 16/8 - I recently tried the IF calculator and am not sure which activity level to use. I do 5-6 hours of activity a week - half strength, half cardio. Dio I just count the cardio = lightly active or all of it = moderately active.

Also - do I only eat the higher calorie amounts on strength days and the lower on my cardio days?

Thanks!

read for yourself, pretty good source as I've read a lot of his articles in the past.
August 8, 2012 7:32 AM
thank you - that site didn't come up in any of my 1 million google searches. :-)

My thoughts are that I wouldn't be able to sustain my exercise programme on the days I only ate 500 calories (for women) and would probably struggle the next day too, so it's of no interest to me.

OK, that did help but I didn't see my specific questions answered.

I don't know what IF site you got this information from, but that is not the way I IF either.

I eat all of my food in about 6-8 hour setting after IF for 16-18 hours.

I've heard that referred to as Alternate Day Caloric Restriction, which differs from IF

Indeed. It would be simpler if we reserved the term "fast" for "zero calorie intake" or similar.

I know what you may want to try, MFP? Set a goal and stick to it. See if that works.
